where to put ActiveModel::Validator?

Question

I try to follow http://api.rubyonrails.org/classes/ActiveModel/Validator.html , but where should I put the

 class MyValidator < ActiveModel::Validator     def validate(record)       if some_complex_logic         record.errors[:base] = "This record is invalid"       end     end      private       def some_complex_logic         # ...       end   end 

Answer 1

This guy puts them under app/validators/, which I've done as well, ever since I saw that blog post.

Answer 2

Add this class in your lib directory and require it in your model and include it inside.
